Well it variates a bit. It isn't a story, so I don't know how else I can do it... I try my best not to make the quests seem pointless to do, and every quest will matter, because when you have done every quest in a category, you will unlock the end quest. If you complete all the end quests, the pack is done, but it will take seriously long time. Like I have said before, the point of this pack is to relax and have fun. Make a world you plan using for a long time. Maybe build epic things, because it is not like crash landing. You are not rushing the quests to get them done, then finish the pack. The quests are supposed to be just a fun addition to modded experience and maybe teach you something about mods you didn't know so much about. Also they will force you to create some items you may have never used before and make a reason for all that honey you have stored over all your hours with bees.
The reason I started creating the pack was because I was getting tired of starting a world over and over again because I run out of ideas. Now I know what I can do and I even get rewarded!
